Q. Write a C++ Program to input a number and then display its multiplication table.

#include<iostream>

#include<conio.h>

int main()

{

int num;

clrscr();

cout<<"Enter a Number to Display\nits Multiplication Table=";

cin>>num;

cout<<"Table of "<<num<<endl<<"................."<<endl;

int i=1;

while(i<=10)

{

cout<<num<<" x "<<i<<" = "<<num*i<<endl;

i++;

}

getch();

return 0;

}

2. Initialize a loop control variable i to 1.

3. Set a while loop with the condition

4.

Let the entered number is 7 and i = 1

5. The statement

6.

int i=1;

while(i<=10)

{

cout<<num<<" x "<<i<<" = "<<num*i<<endl;

i++;

}

This while loop will repeat loop body as long as the condition remains true for the value of i = 1 to 10.

When i becomes 11 then the condition i<=10 takes the form 11<=10 which gives false. Hence loop will stop.

### Logic of the Multiplication Table Program in C++

1. First of all, we input a number to display its table in a variable**num**.2. Initialize a loop control variable i to 1.

3. Set a while loop with the condition

**i<=10 because we wish to repeat loop body for 10 times from i=1 to i=10**4.

**cout<<num<<" x "<<i<<" = "<<num*i<<endl;****The above statement will display one line of multiplication table as follows**Let the entered number is 7 and i = 1

**7 x 1 = 7**5. The statement

**i++;**will cause increment of 1 to i, so that i has the value 2 now.6.

int i=1;

while(i<=10)

{

cout<<num<<" x "<<i<<" = "<<num*i<<endl;

i++;

}

This while loop will repeat loop body as long as the condition remains true for the value of i = 1 to 10.

When i becomes 11 then the condition i<=10 takes the form 11<=10 which gives false. Hence loop will stop.
